Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness technology, specifically a flexible shielded wiring harness for new energy vehicles. Background Technology

[0002] A wiring harness is a group of metal wires and cables bundled together for connecting signals and power between transport equipment. As automobiles become increasingly functional, the number of wiring harnesses used for power transmission is also increasing. For wiring harnesses used in new energy vehicles, it is essential to have good shielding to block interference from high voltage and prevent errors or even interruptions in signal transmission. This can effectively ensure the normal operation of the vehicle and prevent accidents.

[0003] A search of existing published patents (CN202322064208.7) reveals a patent titled "A Flexible Shielded New Energy Vehicle Wiring Harness." The harness includes a main body with connectors at both ends. Several connecting mechanisms are fitted onto the outer wall of the main body. Each connecting mechanism includes a rotating shaft with arc-shaped clamps at both ends. Connecting plates are fixedly connected to the arc-shaped clamps, and connecting screws are provided between the connecting plates. Two nuts are movably fitted onto the outer wall of the connecting screws. A connecting mechanism is provided on the side of each arc-shaped clamp that is far apart from the others. This application, by placing additional wiring harnesses on the surface of a fixing block and controlling the arc-shaped plates to rotate via a rotating shaft, and the pressure plate rotating via a second rotating shaft to adhere to the surface of the wiring harness, and then connecting the crossbar and extension plate with a strap, can fix the position of the wiring harness, avoiding the limitation of only being able to fix wiring harnesses of a fixed size.

[0004] However, the above-mentioned device relies on wires and insulation layers to resist tensile stress during use, which reduces the lifespan of the wiring harness and leaves room for improvement. Utility Model Content
